I've looked in to this and it seems like you can only get the big tooth t5 box or if you want to spend a bit more the tko 600 for a 2wd for reasonable money. Anything else starts to get expensive.

i would love a sequential box in mine but as it's just a road car I've heard they are not nice to drive at low speed and don't like low rpm gear changes so think I will just have a big tooth kit put in my T5 box
